Oh yeah, when I got the 1995 THX set it was like seeing completely new movies. I was finally able to see that Tusken raider Luke saw with his binocs ("there's sandpeople alright, I can see one of them now"). It was also really cool to see things like the scorch marks next to the exhaust port where Red Leader's torpedoes missed. Little things like that. $90 is a ton at that age, but I think you got your money's worth and it sent you down a good path. :)

Side note: zombie, I'm a huge fan of your book and your site, and as I was reading your article about interpositives and film preservation (http://savestarwars.com/filmpreservation.html),

I did some thinking and started this thread: http://originaltrilogy.com/forum/topic.cfm/Trying-to-understand-film-preservation-perhaps-a-stupid-question-but-shouldnt-digital-masters-be-struck-from-theatrical-prints/topic/14944/

Not sure if you saw it, but if you have the time, I'd love to hear your thoughts. The TL;DR basically is: if us fans are trying to preserve what was seen in theaters in 1977, wouldn't we want to scan a theatrical print (as opposed to say an interpositive)?
